Applied bug fix from trunk r1462257.
Applied bug fix from jira issue - OFBIZ-5165 - Broken renderLabel functionality of screenfop view handler. 
If we use label inside widget tag then renderLabel macro skip the label rendering due to wrong condition check.
-- Corrected the conditions for label rendering.
-- Also replaced fo:inline with fo:block as fo:inline can't render directly.
Thanks Deepak.
